Abstract:
An electrostatic spray device for spraying a liquid coating product, including a rotating bowl and a device for driving the bowl around a rotational axis, the bowl defining a concave surface for distributing the coating product and an edge which limits an area for the spraying the coating product. The spray device includes an electrode that charges by ionization of drops of the coating product. The electrode is arranged, in relation to the edge and along the rotational axis, opposite the spray area, between the edge and the device for driving the bowl. A second electrode mounted on a stationary body allows the creation of an electrostatic field for transporting drops. A third electrode, which is also mounted on a stationary body, is brought to an intermediate potential between those of the first and second electrodes during the operation of the spray device.
